University Physics textbook re the 'greenhouse' effect

Thanks to Sky Dragon Slayer IBdaMann for finally (after more than 1000 posts and numerous requests) citing a Physics textbook to try to support his wackjob assertions that the 'greenhouse' effect does not exist, violates the laws of physics, and is a 'religious' belief held by morons, scientific illiterates and 'warmazombies'.

Ironically, all he did was prove that he is the 'scientifically illiterate moron' who hadn't even read the Young and Freedman textbook he cited and totally blew his wackjob assertions out of the water all by himself. For low and behold what do we find toward the end of chapter 17- the very chapter he cited?

17.7 Mechanisms of Heat TransferApplications of Radiation

Radiation, Climate, and Climate Changepages 576-577

"Our planet constantly absorbs radiation coming from the sun. In thermal equilibrium, the rate at which our planet absorbs solar radiation must equal the rate at which it emits radiation into space. The presence of an atmosphere on our planet has a significant effect on this equilibrium.

Most of the radiation emitted by the sun (which has a surface temperature of 5800 K) is in the visible part of the spectrum, to which our atmosphere is transparent.

But the average surface temperature of the earth is only 287 K (14°C).Hence most of the radiation that our planet emits into space is infrared radiation, just like the radiation from the person shown in Fig. 17.28.

However, our atmosphere is not completely transparent to infrared radiation. This is because our atmosphere contains carbon dioxide , which is its fourth most abundant constituent (after nitrogen, oxygen, and argon). Molecules of CO2 in the atmosphere have the property that they absorb some of the infrared radiation coming upward from the surface. They then re-radiate the absorbed energy, but some of the re-radiated energy is directed back down toward the surface instead of escaping into space. In order to maintain thermal equilibrium, the earth's surface must compensate for this by increasing its temperature T and hence its total rate of radiating energy (which is proportional to T ^ 4.)

This phenomenon, called the greenhouse effect, makes our planet's surface temperature about 33°C higher than it would be if there were no atmospheric CO2. If were absent, the earth's average surface temperature would be below the freezing point of water, and life as we know it would be impossible.

While atmospheric CO2 has a beneficial effect, too much of it can have extremely negative consequences. Measurements of air trapped in ancient Antarctic ice show that over the past 650,000 years CO2 has constituted less than 300 parts per million of our atmosphere. Since the beginning of the industrial age, however, the burning of fossil fuels such as coal and petroleum has elevated the atmospheric concentration to unprecedented levels (Fig. 17.29a).

As a consequence, since the 1950s the global average surface temperature has increased by 0.6C and the earth has experienced the hottest years ever recorded (Fig. 17.29b).

If we continue to consume fossil fuels at the same rate, by 2050 the atmospheric concentration will reach 600 parts per million, well off thescale of Fig. 17.29a. The resulting temperature increase will have dramatic effects on climate around the world. In the polar regions massive quantities of ice will melt and run from solid land to the sea, thus raising ocean levels worldwide and threatening the homes and lives of hundreds of millions of people who live near the coast. Coping with these threats is one of the greatest challenges facing 21st century civilization."

I possess a physics textbook that makes no mention of the greenhouse effect. Bought it new in 1959.Titled University Physics, authored by Sears and Zemansky, published by Addison-Wesley, second edition, copyrighted 1955.No mention of greenhouse effect or anything like it. No mention of transistors or artificial satellites or lasers either.

A couple of non-scientists spend all their time posting on the internet that the 'greenhouse' effect violates the laws of physics but can't explain how or show any heat transfer equations or cite any physics textbook that supports their ridiculous claims. They delusionally believe they understand physics more than all the physicists in the world. They claim all the textbooks are wrong or have had 'religious beliefs' sneakily inserted in pdf versions of Physics textbooks by leftist publishers.

Yes that sounds believable-*snort*.

Let's see...where to start...

Heat transfer equations are openly available for anyone who cares to look at them. Maybe you should read the textbook (even the modified one will do) you so love to quote.

Your appeal to authority is a fallacy. It's not even a real authority. Science is not done by consensus.

Your appeal to an extreme argument is a fallacy. No one has claimed all the textbooks are wrong. A textbook is not a final authority either. It is an opinion only.

I really don't care how the page you are quoting was modified, either by you or by a government edict in the current published edition. It matters not. You are the one making it out as a 'massive' conspiracy. At the least you are comparing different editions of the book as being somehow identical.

You are manufacturing a crisis here where there is none. I guess that's the way you get your thrills.

It's 'proof' that the 'greenhouse' effect is discussed in the Physics textbook that IBdaMann cited to support his claim that the 'greenhouse' effect is not found in any Physics textbooks.

Hence his massive fail of shooting himself in the foot.

I could sit here for days and copy and paste excerpts from hundreds of textbooks on Physics and Chemistry, (specifically Atmospheric Physics and Chemistry because that's where it's discussed in more detail) and you would still deny that the physics and chemistry of the 'greenhouse' effect is in every textbook about the physics and chemistry of the atmosphere.

Grow up and go read some goddamned textbooks on the physics and chemistry of the atmosphere instead of ranting about your crackpot pseudoscience opinions all over the internet.

LOL! IbDaMann and Into the Night could use that as 'proof' that the earth is flat and argue you to death with rhetoric and pseuodoscience.

The 'greenhouse' effect may not be mentioned in ALL basic Physics textbooks unless it specifically mentions the earth's atmosphere, and even then, it's not likely to go into much detail.

If someone wanted to understand human anatomy and physiology in depth, they wouldn't learn much from just reading a basic introductory textbook on Biology. They would read textbooks specifically on human anatomy and physiology.

Ceist wrote:If someone wanted to understand human anatomy and physiology in depth, they wouldn't learn much from just reading a basic introductory textbook on Biology. They would read textbooks specifically on human anatomy and physiology. Same thing with the earth's atmosphere.

Global Warming dogma preaches that it is based on very specific science, yet no physics textbook has "The Global Warming example problem" in which those specific mechanisms and models asserted by Global Warming dogma are used to calculate and solve the Global Warming example problem.

Did you notice that?

Ceist - I couldn't agree with you more. But when money and religion are involved, and there are people who value them above all else, then the lies begin.- trafn

You are completely misunderstanding their use of the word "accumulation"!- Climate Scientist.

The Stefan-Boltzman equation doesn't come up with the correct temperature if greenhouse gases are not considered - Hank

:*sigh* Not the "raw data" crap. - Leafsdude

IB STILL hasn't explained what Planck's Law means. Just more hand waving that it applies to everything and more asserting that the greenhouse effect 'violates' it.- Ceist

There is no proof either in science or rhetoric. There is a method of falsifiability in both, however, and Still Learning has provided that. Your argument is blown out of the water by that single example.

You seem to like to use the 'Earth is flat' phrase? Do you really believe anyone is arguing that?

I have textbooks in both meteorology and atmospheric science that makes no mention of greenhouse anything. They were published before 'greenhouse' gases became a fad.

Same thing with the earth's atmosphere.

The gh-theory got it's place in science when mean temperature of earth surface was calculated to 255K. The difference to measured mean of 288K was explained with the cold(!) atmosphere heating(!) surface another 33degrees. Not a degree or two, but a whole 33degrees!

The really scary bit in the story is that those pioneer-scientists and every human that have repeated those conclusions when explaining the theory, did not have the necessary skeptic approach to evaluate the initial number of 255K. Not one of them asked the question: was the calculation applied the right way? Or even worse, not one ofthem were aware of that it is a model of reality where a sun heats a planet, which can only be described with the T^4 formula.Why does anyone think that it is a good idea to replace the laws of radiation with backradiation from cold air?

The surprising conclusions drawn by everyone that know why gh-effect is used instead of the universal temperatureformula, and how it gained place in the model of blackbodyradiation from sun that heats greybody earth, are saying that there is something wrong with the planet and it is so much hotter than it should be.

No one gave Planck, boltzmann or kirchoff credit enough to take a few steps back and ask themselves what the most probable scenario can be:

That nature and the laws of radiation, which is very robust and trustworthy through it's application in both theory and practice, is the correct way of handling this calculation and should not be fiddled with. And that loyalty to the concept must be upheld.

Or: -nature and it's confirmed laws in the models that the masterbrains built for radiation and heat, that is correct for every radiating body in the universe, must be wrong and we have to fix it.

The sun is to weak and we must look for other stuff to get the numbers right. That is a row of several very strange and unscientific conclusions. The brainstorming leading up to the gh-solution can not havet been far from:

-We need stuff that can cover the 33C, suggestions?

-All that icecold air, can't we use that?-I mean, sure it's really cold, but when there is so much of it we can count that as hotter than the sun.

-Yeah, nice one. How much heat does it add?

-Let me calculate, wait a minute.-It should be exactly 33C when the mean troposphere temp of 250K Heats up the surface to 288K. Fits perfectly!

-Nice!

And on top of that, most people that the theory is presented to since then:

-Ok, that seems like the best scientific approach. F*** Boltzmann&Planck, what did they know, right?

Everyone miss that the calculation made to get 255K, and the difference to 288- which is the only thing that justifies GH-theory, produce a very strange earth:

The TSI of 1370W/m^2 is averaged over all of the surface area by dividing it by 4pi*r2.We all know that dividing by 4 gives 4 equal parts, in this case 1370W becomes 240W/m^2.

Remembering that we are making a model of reality we can compare that model to observation and find clues ro the missing 33degrees, but GH-science have an unusually low interest in confirming with observations and instead carefully avoided to think. About anything else than how cool stuff heats up hot stuff to even hotter.

Noone seems to have analyzed why they got 255K .

While dividing by 4pi is common practise when finding a mean, if it is used for earth surface temp, the result is: everyone on earth dies. Because what the model produced is 4 weak suns @240W, heating 4 m^2. Not even red hot suns.

Dividing by four produce 4 weak suns, even if the answer is written as 240/m^2. The other tree parts is also present. When we compare to real measured values we realize that earth should not be @255K, it's an idiot that has that temperature, not earth. And the idea that it gets heat from other stuff than the sun should be the last chosen solution of all.

The reason for the 33degrees is entirely a product of lacking understanding for physics. A model of 4 suns must be the record failure of all science.

And here is how it should be done:

@288K confirmed mean temperature the fluxdensity needed in 1m^2 that heats 2m^2(1/2 sphere heated for the whole sphere mean), is ~1000W at sea level. And that is the peak effect in the waveform, like 288K is peak in surface temp mean, when shown as blackbody curve of earth. So there's no need for evenly distributed 1000W over all surface heated. Just always present in a fraction of the surface.

1000W is measured about everywhere on earth, it is the number we need, it is much better than 4 suns in cold darkness.

I see no other heat source, just the sun, so I draw the conclusions that all of it comes from the sun. The craziest thing to do, is looking for cold air to heat the surface. It is not a secret that we get 1000W as a common observed value. Solar cells are often calibrated to that number. Not without reason.

With a surface emissivity of 0.8 we get

1000W/m^2=

(0.8*5.67*10^-8 * 364K^4)/2m^2=

(5.67*10^-8 * 290K^4)=

400W/m^2

No GH-fudge, no model of a heat source like the 4 weak suns that don't shine, in icecold darkness. No missing 33C, no covering up of the unaware incompetence by using icecold gas for heating.

And it fits perfect.

GH-theory choosed a path to the solution of cold gas heating a warm earth even if that is the absolute worst available solution.

It is the most embarrassing thing that has happened in science history.

GH-theory! From the departements of science that build models that break laws of nature with precision. Nothing in it is right.

The brainstorming leading up to it can not be far from:

-We need some more heat in the theory, numbers don't add up. And by the way, shouldn't those 4 suns be shining? They seem a bit colder than the real sun.

-Hell no, they are exactly as hot as the sun, we know that because I calculated it to 255K. Nature is like that. Weird and disobedient of natures laws. Ignore it.

-Use cold air instead, that is the best way to solve the problem. Also, use water as heater. You know, like we always pour water on hot things to heat them up even more.

Ceist wrote:According to Into the Night, it would be a logical fallacy to cite a University textbook on Atmospheric Physics and Chemistry when discussing the physics and chemistry of the atmosphere.

But accepting everything an anonymous layperson claims on the internet about a subject he clearly knows nothing about, is 'logical'.

What about not even noticing that the whole foundation for a theory that is proclaimed as truth, is the incompetent calculation that gives a model of earth temperature that is 4 suns not even red hot. And based on that earth model where it floats in icecold darkness, solves the problem with cold air, backradiation of photons which we know can't be included in calculation of heat transfer. The transfer of heat from cold to hot via photons, must not even be part of heat transfer in theory or practise when we samt correct results. There is no question about that.

But that doesn't stop the gh-science from doing just that, and when asked to explain we learn that cold air is not different from blancets and sleeping bags, keeping us warm and cozy.

Just like you choose between sleeping bag and cold air when you go to sleepi in your tent.

Photons heat surface because....

. .. molecules in cold air radiates in all directions.

And we don't need walls in furnaces, a sleeping bag or even better, cold air, is a really good insulator @ -18C, if surrounded with the vacuum of space @ 3K. The lack of conducting walls seems like not a problem to earth.

While design of insulation always looks different than cold air and the ideal heat sink of space on top of that, the atmosphere would never bend to such laws of nature. Barriers for insulation keeping air in place, can be replaced with unrestricted air moving fast and freely when insulating earth.
